Regarding the resistance of the ASCO solenoid valve
Thread Content
What is the typical resistance value of ASCO solenoids, which are low-power and powered by 24VDC?
Does no one know? We have an ASCO solenoid valve here; I removed it to measure the coil resistance, which is a little over 4 million ohms. I’m not sure how to determine whether this solenoid valve is good or bad
4M ohms – it seems the coil is almost completely burned out.
Unplug one wire from the good solenoid valve and measure its resistance to find out. Also, the coil should be insulated from the housing; if current flows through it, it will definitely burn out.
How many ohms does a normal solenoid coil have?
Coil resistance: 410 ohms (20°C, voltage tolerance: ±10%)
The resistance value is too high; it’s likely damaged. If it’s hard to determine, just test the spare one
ASCO solenoid valve, low power consumption, powered by 24VDC. It can be calculated: for low-power devices, the power consumption is generally below 2 watts. Assuming 2 watts, IIR = W, and R = U*U/w = 24*24/2 = 288 ohms.
Different models and specifications vary; it is generally around a few hundred ohms.
It’s usually a few hundred ohms, but when you measured it, were you using the circuit board with the indicator there?
